Compose Advanced Graphics Effects With SwiftUI

This article covers Apple's WWDC26 session on composing advanced graphics effects with SwiftUI, emphasizing subtle, performance-aware enhancements. It explains how to use Shader, ShaderLibrary, and Metal stitchable functions for effects like .colorEffect, .distortionEffect, and .layerEffect. The example builds a now-playing screen with synchronized transcript rows, where the artwork gets a time-driven layer effect while the transcript remains standard SwiftUI text. Key topics include passing small values to shaders, declaring honest maxSampleOffset, keeping effect boundaries narrow, and using layout state and alignment guides. The article provides code snippets for modeling transcript data, managing playback state, and integrating effects without compromising accessibility or Dynamic Type.
